Longines Spirit 40mm L3.810.4.73.2 Watch Review

The Longines Spirit watch collection doesn’t fit into the Longines category of classic Swiss luxury flair timepieces. The Longines Spirit collection represents a sportier category, combined with the Longines heritage. The collection has been praised for being a “pioneer spirit” in celebrating the iconic aviators and legendary adventurers. These legends are believed to have used Longines devices during their escapades. The Spirit collection is inspired by watches used during that time era. Longines borrowed the concept of that era to come up with modern watches representing the legendary figures. The Longines Spirit collection is comprised of modern timepieces that are vintage-inspired, having modern appeal combined with a mid-twentieth century military and pilot feel. The collection represents a luxurious take on aviator’s watches used in the 20th century.


The Longines Spirit 40mm L3.810.4.73.2 model is one of the extraordinary timepieces in the Longines Spirit collection. The 40mm model is more affordable compared to the other watches in the Spirit collection.


The case has a handsome finishing thanks to the mix of classic lines found in the Spirit collection, and it comes in medium size of 40 x 49.6 x 12.5mm. The watch has gently contoured sides and robust lugs, which have a beautifully textured brushing. The finishing of the case is one of the beautiful features of the watch. Sharp bezels are used to accentuate the robust lugs. The case of the Longines Spirit 40mm L3.810.4.73.2 model has slight angles and curves with a domed sapphire finishing. The round-shaped case is made of stainless steel.

The case has a sapphire crystal glass. Both sides of the glass are layered with an anti-reflective coating. The sapphire crystal glass is scratch-resistant. The case has a 12.5mm height, carefully hidden by the case breaks, crystal, and the various finishing lines. Off at the 3 o'clock marker, there is a screw-down crown. The crown tapers into the watch's case, and the outer face of the case has a detailed etching. The watch has a water resistance level of 10 bar.

The back of the case is relatively flat. There are six small screws used to hold it into place. The back case has a globe etching with latitude and longitude lines, adorned with a winged hourglass.

Dial & Hands

The dial is pale silver-white, and the surface of the dial is split between a chapter ring and the lower dial, which have been given different finishing. The primary index of the watch has largely applied numerals found on the lower dial. The 3 numeral has been skipped, leaving room for the date window. The silver dial of the watch works well with any color.

On the outer part of every marker, there are small diamonds of lume. The minutes/seconds index are finely printed inside a closed circle just above the chapter ring. Under the 12 o’clock marker, you see the Longines marker and "automatic." At the 6 o’clock marker is a "chronometer” read, featuring five polished stars.

The hour and minute hand of the Longines Spirit 40mm L3.810.4.73.2 model are thin buttons which have been filled with lume. They are rendered in matte black metal. The second's hand is more of a stick, in matte black, with a small tip that is lume filled, featuring red paint on its last third.

Movement & Functions

The Longines Spirit 40mm L3.810.4.73.2 model uses the L888.4 caliber, a new caliber used by Longines. The watch’s caliber is based on the caliber ETA 2892-A2. The L888.4 caliber features a power reserve that is expanded, 64 hours. It also has a frequency of 25,200 vibrations per hour and a monocrystalline silicon balance spring. The watch is automatic, with a self-winding movement mechanism. The watch has a chronometer certification by COSC. This means that the Longines Spirit 40mm L3.810.4.73.2 model is very accurate with an accuracy of -4/+6 seconds daily in six positions.


The leather strap is 21mm and made of cognac-colored leather. The strap has embroidered edges with a little padding, and it is tapered down to 18mm, with a chiseled tip. This gives the watch a vintage, more rugged look. The strap has a thumbnail buckle with a brushed and polished surface. The watch has a lug to lug, which is long.

The Longines Spirit 40mm L3.810.4.73.2 model is indeed a winner when it comes to style and looks. The watch dresses up the 20th-century aviation/military aesthetic with some glitz mostly seen on Swiss luxury watches.
